The text of 1S0 Standard has been approved as suitable for publication as an Indian Standard without deviations. Certain terminology and conventions are, however, not identical to those used in the Indian Standards. Attention is drawn especially to the following: a) Wherever the words `International Standard' appear, referring to this standard, they should be read as `Indian standard' . b) Comma (,) has been used as a decimal marker while in Indian Standards the current practice to use a full point (,) as the decimal marker. The concerned Technical Committee has reviewed the provisions of the following International Standards refemd in this adopted standard and has decided that they are acceptable for use in conjunction with this standard: International Standard EN 1904:1995 1S0 4481:1977 BIS CERTIFICATION MARKING Details available with the Bureau of Indian Standards. For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance with IS 2:1960 `Rules for rounding off numerical values (revised)', The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard.

IS 15104 (Part 8) :2004 ISO" 8442-8:2000 Annex D (normative) Test methods for strength of attachments D.1 Principle Attachments to holloware are examined for breakage, deformation or disengagement resulting from the application of a force simulating that likely to occur as the result of a minor abuse such as dropping. D.2 Apparatus D.2.1 Load, metal weight of mass 10 kg * 0,01 kg suspended from a cord terminating in a loop or clamp. D.3 Procedure D.3.1 Loop the cord around, or clamp it to, the attachment to be tested and raise the test specimen so that the weight is in free suspension with its mass acting vertically downwards. D.3.2 Rotate the test specimen so that the force is transfen-ed to all relevant points on the attachment and record any breakage, deformation or disengagement of the attachment. 9 IS 15104 (Part 8) :2004 ISO 8442-8:2000 Annex E (normative) Test method for pouring E.1 Principle The pouring efficiency of spouts is evaluated by tilting the vessel, filled to its usable capacity with water, at a controlled rate. NOTE Traces of detergent from washing processes promote dribbling; any vessel which has been washed with the aid of a detergent should be thoroughly rinsed not less than five times in deionized water prior to testing for pouring efficiency. E.2 Apparatus E.2.1 T]lt platform, capable of traversing an angleof700 at (5 k 1) "/min. E.3 Procedure E.3.1 With the platform in the horizontal position, place the specimen under test upon it (suitably restrained, e.g. by means of a large rubber band) and fill it to within 15 mm Y 1 mm of the rim with deionized water at 20 `C & 5 "C. Tilt the platform at 50 & 10 per minute so that water emerges only from the spout, until an angle of 100 ~ 1 0 to the horizontal is reached. Record the form of pouring which takes place. Return the platform to the horizontal position at the same speed and record whether dribbling down the outside of the test specimen occurs. NOTE If water emerges over the rim of a vessel in this test, the pouring angle should be reduced progressively until this no longer occurs. E.3.2 Repeat the procedure described in E.3. 1 for angles increasing successively by 100 & 10 to a maximum of 700. . 10 IS 15104 (Part 8) :2004 ISO 8442-8:2000 Annex F (normative) Method of test for handle temperature F.1 Principle and apparatus Fill the tank (e.g. tea-pot) to its usable capacity with hot water simulating its use in service and measure the maximum temperature reached by the handleusing a therrnoeouple, accurate to *3 `C in the range 30 `C to 100 "C and consisting of a surface contact probe capable of being held in intimate contact with the handle. 11 IS 15104 (Part 81:2004 ISO 8442-8:2000 Annex G (informative) A-deviations A-deviation: National deviation due to regulations, the alteration of which is for the time being outside the competence of the CEN/CENELEC member.
